[1] The term was used by activist Karl Heinrich Ulrichs in a series of five booklets from 1864 to 1865 collected under the title Forschungen über das Räthsel der mannmännlichen Liebe (The Riddle of Man–Manly Love).
[2] The term uranian was adopted by English-language advocates of homosexual emancipation in the Victorian era, such as Edward Carpenter and John Addington Symonds, who used it to describe a comradely love that would bring about true democracy.
[3][4] Oscar Wilde once wrote to his lover Robert Ross in an undated letter, "To have altered my life would have been to have admitted that uranian love is ignoble.
Ulrichs derived uranian (Urning in German) from a dialogue on eros, in particular male love, metaphorized by the birth of Greek goddess Aphrodite from Plato's work Symposium.
Urning was derived from Aphrodite Urania, who was created out of the god Uranus' semen, a birth in which "female has no part", therefore representing love between men.
